From George Busk 24 November 1871
Summary
Thanks for information on platycnemic tibiae found in America. Believes the condition is of two kinds as exemplified by Gibraltar and Cro-Magnon tibiae on one side and the Welsh form on the other. Would like to know which of the two forms the American bones are; their proportions suggest they are very like the Welsh tibiae.
